Delaunay mesh surface with oculus

hello everyone !! am a beginner using grasshopper, I need help if it is possible !!! I am using ‘Delaunay mesh’ and as mentioned in the attached picture the mesh is surrounding all the surface.
so, is there any possibility to create an oculus on it?
ps: the rail revolution is defined correctly.


Possibly with the QuadRemesh or TriRemesh tools… you could use the points and edge curves as inputs.

Towards the end of this discussion there’s some similar ideas…

I think the easiest way would be to use Cull Faces on the mesh.
You can identify the faces to remove by projecting their centres and checking if they are less than a given distance from the centre, or if they are contained by the inner circle.
